Description

Technical Field

[0001] The present invention relates to the technical field of steering knuckle processing, and in particular to a device and method for processing surface discoloration during steering knuckle processing. Background Art

[0002] The steering knuckle, also known as the "knuckle," is a critical component in a vehicle's steering axle, ensuring stable driving and sensitively transmitting direction. Its function is to transmit and bear the front load of the vehicle, supporting and driving the front wheels around the kingpin to steer the vehicle. While the vehicle is in motion, it is subject to variable impact loads, requiring it to possess exceptional strength.

[0003] In the prior art, due to the high strength requirements of the steering knuckle, a forging process is often used to manufacture it. The blank is heated and then forged. The surface of the blank will oxidize and discolor due to contact with air, which greatly reduces the surface quality of the finished forging.

[0004] Existing methods for treating surface discoloration of steering knuckles include mechanical friction, pickling, high-pressure water washing, shot blasting, etc. Among them, pickling treatment has ideal effect and consumes less metal. Pickling generally involves immersing the steering knuckle in an acidic cleaning solution of a certain temperature and concentration and ultrasonically vibrating it to remove surface discoloration. After the surface discoloration layer is completely removed, it is rinsed with clean water to remove the surface acid residue, and then dried and packaged. In the existing technology, the steering knuckles are generally moved manually into and out of different cleaning tanks for cleaning. Only one steering knuckle can be moved at a time. Not only is the labor intensity high and the operating efficiency low, but frequent contact with the acidic cleaning solution will cause significant damage to the skin. Even with gloves, the hands will feel uncomfortable due to the lack of air permeability during frequent operations for a long time, which urgently needs improvement. Summary of the Invention

[0005] The purpose of the present invention is to provide a device and method for treating surface discoloration during steering knuckle processing, which effectively solves the problems of high manual labor intensity and skin damage caused by frequent contact of human hands with cleaning fluid. It has the advantages of simple structure, easy operation, low manual labor intensity and high work efficiency.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A device for treating surface discoloration during the processing of a steering knuckle, comprising four receiving slots with top openings and a turntable for mounting the receiving slots, wherein the four receiving slots are arranged in a circular array above the turntable and are fixedly connected to the turntable, the center of the turntable being rotatably connected to a machine body via a rotating shaft, a cover plate being provided above the turntable, an operating port being provided on the cover plate, the operating port being located on the circumference of the circle where the movement trajectory of the receiving slots is located, the size of the operating port matching the size of the top opening of the receiving slot, a flip clamping mechanism being provided above the operating port for placing the steering knuckle into the receiving slot, the flip clamping mechanism being connected to a flip driving mechanism.

[0008] By adopting the above technical scheme, the four receiving tanks are respectively used for pickling, alkali neutralization, water rinsing and drying the steering knuckle with discolored surface, thereby realizing the treatment of the steering knuckle with discolored surface, the operating port on the cover plate is used to realize the steering knuckle to enter and exit the respective receiving tanks, the flip clamping mechanism is used to clamp the steering knuckle and drive the steering knuckle to flip up and down under the drive of the flip driving mechanism, thereby realizing the steering knuckle to be switched to different receiving tanks for pickling, alkali neutralization, water rinsing and drying operations at one time, and during the whole process, it is only necessary to clamp the steering knuckle to be treated and remove the treated steering knuckle, and human hands do not need to enter the receiving tank and will not come into contact with the cleaning liquid, which greatly reduces the harm of the cleaning liquid to the human body, and the steering knuckle automatically flips and switches to different receiving tanks for immersion corresponding operations, and there is no need for people to frequently move the steering knuckle in and out of the receiving tanks, which greatly reduces the labor intensity of people and improves work efficiency.

[0009] The present invention is further configured as follows: the flip clamping mechanism is horizontally arranged with a flip axis, one end of the flip axis is connected to the cover plate through a bearing seat, and the other end of the flip axis is connected to the flip driving mechanism, and the flip axis is provided with a clamping mechanism for clamping the steering knuckle, and the clamping mechanism includes an arc-shaped clamping arm 1 and an arc-shaped clamping arm 2 for clamping or releasing the steering knuckle, the upper ends of the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2 are rotatably connected to the connecting rod, the middle ends of the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2 are respectively provided with arc grooves that slide with the driving rod 1 and the driving rod 2, the arc grooves of the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2 are respectively slidably connected with the driving rod 1 and the driving rod 2, and the lower ends of the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2 are respectively provided with clamping parts for clamping the steering knuckle, and the connecting rod, driving rod 1 and driving rod 2 are all parallel to the flip axis.

[0010] By adopting the above technical solution, the clamping mechanism on the flip shaft clamps the steering knuckle to be processed, and then the flip shaft is driven by the flip driving mechanism to rotate so that the steering knuckle flips up and down with the clamping mechanism. When the steering knuckle rotates gradually from the highest position to the lower position, the corresponding receiving groove will rotate with the turntable to the bottom of the steering knuckle until the steering knuckle reaches the bottom of the receiving groove for pickling, alkali neutralization, water rinsing and drying operations. When the steering knuckle moves from the bottom of the receiving groove to the top of the receiving groove, the turntable starts to rotate as the steering knuckle continues to move, so that the next receiving groove approaches the position opposite to the steering knuckle until the steering knuckle rotates from the highest position to the lower position again and the receiving groove just reaches the bottom of the steering knuckle. This is repeated until the steering knuckle passes through four receiving grooves in sequence, thereby completing a working cycle. The driving rod 1 and the driving rod 2 in the clamping mechanism are used to drive the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2 to rotate in the same direction or opposite direction around the connecting rod, so that the clamping parts on the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2 are used to clamp or release the steering knuckle. The structure is simple and the operation is convenient.

[0011] The present invention is further configured as follows: the clamping mechanism also includes an X-shaped connecting rod structure and a support ring respectively arranged at both ends of the flip shaft, the X-shaped connecting rod structure includes a connecting rod 1 and a connecting rod 2 arranged crosswise with each other, the connecting rod 1 and the connecting rod 2 are connected by a spring, the middle parts of the connecting rod 1 and the connecting rod 2 are both rotatably connected to the flip shaft, the two ends of the connecting rod 1 and the connecting rod 2 are both slidably matched with the annular groove on the inner wall of the support ring, the same end of the connecting rod 1 and the connecting rod 2 is fixed with a gravity ball 1 and a gravity ball 2, the other ends of the connecting rod 1 and the connecting rod 2 are respectively fixedly connected to the end of the driving rod 1 and the driving rod 2, and the two ends of the connecting rod are respectively fixedly connected to the top of the two support rings.

[0012] When the cam is rotated, the driving shaft is rotated and the driving shaft is rotated, so that the driving shaft is rotated synchronously with the driving shaft, and the driving shaft is rotated synchronously with the driving shaft. When the driving shaft is rotated synchronously, the driving shaft is driven to rotate synchronously with the X-shaped connecting rod structure at both ends of the rotating shaft, the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2, and the clamping parts provided at the lower ends of the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2. When the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2 are flipped, the steering knuckle clamped by the clamping parts at their lower ends is flipped synchronously. When the X-shaped connecting rod structure is flipped, the gravity balls 1 and the gravity balls 2 on the connecting rod 1 and the connecting rod 2 in the X-shaped connecting rod structure will flip synchronously with the connecting rod 1 and the connecting rod 2 respectively. When the gravity balls 1 and the gravity balls 2 are flipped to the top of the flip shaft, the ends of the connecting rod 1 and the connecting rod 2 will move in the directions away from each other, thereby causing the driving shaft 1 and the driving shaft 2 fixedly connected to the connecting rod 1 and the connecting rod 2 respectively to move in the directions away from each other, driving the cam to rotate synchronously with the driving shaft When the movable shaft one and the driving shaft two respectively move in directions away from each other, the arc-shaped clamping arm one and the arc-shaped clamping arm two will be driven to move in directions away from each other, so that the clamping parts on the arc-shaped clamping arm one and the arc-shaped clamping arm two will loosen the steering knuckle, so as to facilitate the loading and unloading operations of the steering knuckle. When the gravity ball one and the gravity ball two flip to the bottom of the flip shaft, the ends of the connecting rod one and the connecting rod two will move in directions approaching each other, so that the driving shaft one and the driving shaft two respectively fixedly connected to the connecting rod one and the connecting rod two will move in directions approaching each other. When the driving shaft one and the driving shaft two respectively move in directions approaching each other, the arc-shaped clamping arm one and the arc-shaped clamping arm two will be driven to move in directions approaching each other, so that the clamping parts on the arc-shaped clamping arm one and the arc-shaped clamping arm two will tighten the steering knuckle to prevent the steering knuckle from falling. The arc-shaped clamping arm one and the arc-shaped clamping arm two are controlled by the gravity ball to approach or move away from each other, so as to achieve clamping or loosening of the steering knuckle. The structure is simple and the operation is convenient.

[0013] The present invention is further configured as follows: the clamping portion includes a limit block 1 and a limit block 2, which are respectively arranged at the ends of the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2; the limit block 1 is provided with a support rod matching the bearing hole of the steering knuckle body on the side close to the limit block 2; a through hole is provided on the limit block 2 at a position opposite to the support rod on the limit block 1.

[0014] By adopting the above technical solution, the limit block one and the limit block two are used to limit the clamping position of the steering knuckle, so that the steering knuckle will not slide arbitrarily along the arc-shaped clamping arm one and the arc-shaped clamping arm two, avoiding the problem of collision between the steering knuckle and the tilt shaft or other mechanical mechanisms. The support rod is used to support the steering knuckle, and the support rod matches the bearing hole of the steering knuckle main body, so that the steering knuckle will not shake arbitrarily after being supported by the support rod, effectively improving the stability of the steering knuckle clamping. When the steering knuckle is clamped, the limit block one and the limit block two move closer to each other along the arc-shaped clamping arm one and the arc-shaped clamping arm two, so that one end of the support rod moves axially to a position close to the through hole and is inserted into the through hole. At this time, the steering knuckle will not slide out of one end of the support rod and fall off. When the steering knuckle is released, the limit block one and the limit block two move away from each other along the arc-shaped clamping arm one and the arc-shaped clamping arm two, so that one end of the support rod moves axially to a position away from the through hole and leaves the through hole. At this time, the steering knuckle can be conveniently removed from the support rod. The structure is simple and the operation is convenient.

[0015] The present invention is further configured as follows: the arc-shaped clamping arm 1 and the arc-shaped clamping arm 2 include multiple groups, the connecting rod is provided with multiple spacers, and each group of arc-shaped clamping arm 1 and arc-shaped clamping arm 2 is separated by a spacer.

[0016] By adopting the above technical solution, multiple groups of arc-shaped clamping arms 1 and arc-shaped clamping arms 2 can achieve the simultaneous clamping or release of multiple steering knuckles, thereby realizing the simultaneous processing of multiple steering knuckles, further improving production efficiency. The setting of the spacer makes the arc-shaped clamping arms 1 and arc-shaped clamping arms 2 in each group independent of each other, thereby ensuring that multiple steering knuckles do not affect each other during the simultaneous processing process, effectively ensuring the reliability of equipment operation.

[0017] The present invention is further configured as follows: the flipping drive mechanism includes a driving shaft fixed at the rotation center of the turntable, the upper end of the driving shaft passes through the cover plate and is rotatably connected to the cover plate, the end of the driving shaft located above the cover plate is fixed with a bevel gear 1, the bevel gear 1 is meshed with the bevel gear 2, the bevel gear 2 is coaxial with the gear and is fixedly connected to the support shaft, one end of the support shaft is connected to the driving motor, and the gear 1 is meshed with the gear 2 fixed on the flipping shaft.

[0018] By adopting the above technical solution, the driving motor drives the support shaft to rotate. When the support shaft rotates, it drives the bevel gear 2 and gear 1 fixedly connected thereto to rotate synchronously. When the bevel gear 2 rotates, it drives the bevel gear 1 meshed with it to rotate. When the gear 1 rotates, it drives the gear 2 meshed with it to rotate. When the gear 2 rotates, it drives the flip shaft fixedly connected thereto to rotate. When the bevel gear 1 rotates, it drives the drive shaft fixedly connected thereto to rotate. When the drive shaft rotates, it drives the turntable to rotate.

[0019] The present invention is further configured as follows: the bevel gear 1, bevel gear 2, gear 1 and gear 2 are all located in a sealed housing, the housing is fixed on the cover plate, the flip shaft, support shaft and drive shaft are all rotatably connected to the housing, and the drive motor is fixed on the housing.

[0020] By adopting the above technical solution, the sealed housing is used to protect driving components such as bevel gear 1, bevel gear 2, gear 1 and gear 2, thereby greatly reducing the corrosion of driving components such as bevel gear 1, bevel gear 2, gear 1 and gear 2 caused by the volatilization of acidic cleaning liquid, thereby effectively improving the service life of the equipment.

[0021] The present invention is further configured as follows: only half of the teeth are provided on the second bevel gear.

[0022] By adopting the above technical solution, only half of the teeth are provided on bevel gear 2, so that when bevel gear 2 rotates continuously, bevel gear 1 meshing with bevel gear 2 rotates intermittently, and gear 1 coaxial with bevel gear 2 drives gear 2 meshing with it to rotate continuously, so that when the flip shaft fixedly connected to gear 2 rotates continuously, the drive shaft fixedly connected to bevel gear 1 rotates intermittently. Therefore, it can be achieved that when the flip shaft flips the steering knuckle into the receiving groove until the steering knuckle leaves the receiving groove, the receiving groove will not rotate with the turntable. When the flip shaft flips the steering knuckle to leave the receiving groove, the receiving groove will rotate with the turntable until the next receiving groove rotates to the bottom of the flip shaft, avoiding the steering knuckle rotating with the receiving groove after entering the receiving groove and causing interference, thereby further improving the reliability of the equipment.

[0023] The present invention is further configured as follows: three consecutive holding tanks for holding liquids in the four holding tanks are each provided with an ultrasonic generator, an electric heating tube and a temperature sensor; one holding tank is provided with a plurality of injection tubes, and the injection tubes are connected to a high-temperature gas source.

[0024] By adopting the above technical solution, the ultrasonic generator is used to combine the "physical operation" of ultrasound and the "chemical action" of the cleaning agent during the process of pickling, alkali neutralization and clean water rinsing to achieve a cleaning effect with better cleaning effect. The jet pipe is used to spray high-temperature gas onto the steering knuckle after cleaning, so that the moisture on the surface of the steering knuckle is instantly removed to prevent the steering knuckle from being oxidized or rusted again. At the same time, the dried steering knuckle will not cause damage to human skin, killing two birds with one stone.

[0025] A method for treating surface discoloration during steering knuckle processing, characterized in that it comprises the following steps:

[0026] Step S1: Pour equal amounts of clean water into the holding tanks of the two electric heating tubes and the temperature sensor, and then add a certain amount of weak acid cleaning agent and alkaline neutralizer to the clean water of the first two holding tanks in the direction of rotation of the holding tank and stir them evenly;

[0027] Step S2: controlling the electric heating tube and the temperature sensor to be energized so that the temperature of the liquid in the two accommodating chambers is increased and maintained in the range of 40° C. to 60° C.;

[0028] Step S3: Fix multiple steering knuckles to be processed on the clamping mechanism, and then start the drive motor and the high-temperature air source control valve at the same time. The drive motor drives the flip shaft to drive the steering knuckle fixed on the clamping mechanism to flip continuously. At the same time, the turntable drives each receiving tank to pass under the steering knuckle on the clamping mechanism in turn, so that the steering knuckle on the clamping mechanism is respectively in contact with the weak acid cleaning solution, alkali neutralization solution and clean water in each receiving tank and then blown dry by the high-temperature air source.

[0029] Step S4: removing the dried steering knuckle from the clamping mechanism and fixing the next set of steering knuckles to be processed on the clamping mechanism.

[0030] The beneficial effects of the present invention are:

[0031] 1. The present invention uses four receiving tanks to perform pickling, alkali neutralization, water rinsing and drying operations on the steering knuckle with discolored surface, thereby realizing the treatment of the steering knuckle with discolored surface; the operating port on the cover plate is used to enable the steering knuckle to enter and exit the receiving tanks; the flip clamping mechanism is used to clamp the steering knuckle and drive the steering knuckle to flip up and down under the drive of the flip driving mechanism, thereby realizing the operation of switching the steering knuckle to different receiving tanks for pickling, alkali neutralization, water rinsing and drying at one time; during the whole process, it is only necessary to clamp the steering knuckle to be treated and remove the treated steering knuckle; there is no need for human hands to enter the receiving tank and will not come into contact with the cleaning liquid, which greatly reduces the harm of the cleaning liquid to the human body; and the steering knuckle automatically flips and switches to different receiving tanks for immersion corresponding operations, without the need for people to frequently move the steering knuckle in and out of the receiving tanks, which greatly reduces the labor intensity of people and improves work efficiency.

[0032] 2. The present invention uses the gravity of gravity ball 1 and gravity ball 2 as they flip along the flip axis to cause the ends of connecting rod 1 and connecting rod 2 to move toward or away from each other, thereby causing drive shaft 1 and drive shaft 2, which are respectively fixed to connecting rod 1 and connecting rod 2, to move toward or away from each other. By causing drive shaft 1 and drive shaft 2 to move toward or away from each other, arc-shaped clamping arm 1 and arc-shaped clamping arm 2 are driven to move toward each other, thereby causing the clamping parts on arc-shaped clamping arm 1 and arc-shaped clamping arm 2 to tighten or loosen the steering knuckle. The structure is simple and the operation is convenient.

[0033] 3. The present invention provides only half of the teeth on bevel gear 2, so that when bevel gear 2 rotates continuously, bevel gear 1 meshing with bevel gear 2 rotates intermittently, and gear 1 coaxial with bevel gear 2 drives gear 2 meshing with it to rotate continuously, so that when the flip shaft fixedly connected to gear 2 rotates continuously, the driving shaft fixedly connected to bevel gear 1 rotates intermittently. Therefore, when the flip shaft flips the steering knuckle into the accommodating groove until the steering knuckle leaves the accommodating groove, the accommodating groove will not rotate with the turntable. When the flip shaft flips the steering knuckle to leave the accommodating groove, the accommodating groove will rotate with the turntable until the next accommodating groove rotates to the bottom of the flip shaft, avoiding interference caused by the steering knuckle rotating together with the accommodating groove after entering the accommodating groove, thereby further improving the reliability of the equipment.
